Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a recommendation for a first codebook that is for a single transmit receive point (TRP) and that does not include a time domain (TD) or Doppler domain (DD) basis, or for a second codebook that is for multiple TRPs or that includes a TD or DD basis. The UE may transmit the recommendation. Numerous other aspects are described.
Claims30
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory comprising instructions executable by the one or more processors to cause the UE to:
- generate a recommendation for a first codebook that is for a single transmit receive point (TRP) and that does not include a time domain (TD) or Doppler domain (DD) basis, or for a second codebook that is for multiple TRPs or that includes a TD or DD basis;
- and
- transmit the recommendation.
A network entity for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory comprising instructions executable by the one or more processors to cause the network entity to:
- receive a recommendation for a first codebook that is for a single transmit receive point (TRP) and that does not include a time domain (TD) or Doppler domain (DD) basis, or for a second codebook that is for multiple TRPs or that includes a TD or DD basis;
- and
- transmit a codebook configuration that is based at least in part on the recommendation.
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory comprising instructions executable by the one or more processors to cause the UE to:
- receive a codebook structure for selecting a time domain (TD) or Doppler domain (DD) basis for a codebook based at least in part on one or more configuration conditions;
- and
- select the TD or DD basis for the codebook based at least in part on a comparison of one or more current conditions and the one or more configuration conditions.
A network entity for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory comprising instructions executable by the one or more processors to cause the network entity to:
- generate a codebook structure for selecting a time domain (TD) or Doppler domain (DD) basis for a codebook based at least in part on one or more configuration conditions;
- and
- transmit the codebook structure.
